Arena Allocator

An educational C project demonstrating how an arena allocator works using operating system-level memory reservation and commitment patterns.

Overview

This project provides a practical implementation of an arena allocator, also known as a linear or bump allocator. It's designed to illustrate memory management concepts and serves as a learning resource for understanding efficient memory allocation strategies.

Features

• Linear/arena-based memory allocation model
• OS-level memory reservation and commitment
• Minimal dependencies (pure C)
• Educational and well-structured codebase

Building

Using Make

make
./build/arena-allocator

Using CMake

cmake -S . -B build
cmake --build build -- -j
./build/arena-allocator
